Should there be considerable wear at this point, a pull upon the rod causes the end niembe 5 to tenipmarily pivot about the wrrer 15 since this naturally the portion which comes in c ntact first. This pivoting action throws the lower end of the member up and, theref re, throws the band out of ament with the drum, bat the iriciaf grip of the drum on its opposite side again causes a pull of the band to its face. This action may tillfl} place a number of times before the band is in its correct gripp tion and is what is termed chatter. in order that this chatter may be overcome, i have provided the cover piece with a screw 2 extending into the slotted portion with head i? lowermost. The pull rod 6 being tationary as far as its up and down movement is concerned, the head of the screw 16 i caused to hear on this rod and conse :1; the corner is held innnovable is up and down movement with resp ct to the drum itself. Therefore, should ihis portion of the end IHOH'ilJQl' be worn and m invention applied, the chatter can never be causeifi. because of this wear, for the rean that the srreiv l6 wilt prevent up and may iimveinent of the i'i'iei'nber 5 and conly its temporary pivotal movement the corner L2- is, of course, underthat when. my invention is applied to i new d rice, no unusual amount of wear can ha at this point. A loci; nut 18 may be provided to guard against accidental rel iase oi the screws 16, or this same screw may be held by a set screw 19, or both may be used it desired. It is essential, however, that no type of locking arrangement be pro vided in order that the vibrations may not cause release movement of the screws 16.

hat I claim, is:

l. i band brake comprising a drum, a brake band encircling said drum, one end of said band being movable While the other end is held stationary, an end member for the stationary end oi said band, an abutment against which said member acts to hold it stationary, an HlltWifl'til extending slotted ear for said end member, an operating rod attached to the movable end of said band and adapted to pass through the slot in said end member, and adjusting means for positively limiting the play of said rod up and down in the slot of said member.

A band brake comprising a drum, a brake band encircling said drum, one end of said band being movable while the other end is held stationary, an end member for the stationary end of said band, an abutment against which said member acts to hold it stationary, an outwardly extending ear on said member provided with an open ended slot, an operating rod attached to the movable end of said band and adapted to pass through the siot in eai-l end member, a cover pierxe for the open end of said slot rigidly held in position, a screw passing through said cover piece and into said slot and adapted to adjustably 3 rar on said rod to limit its play up and down in said slot, and means for locking: said rerew in any adjusted position.

In testimony whereof I alliX my signature in the presence ol two witnesses.
